Final answer:
In the scenario of a zombie apocalypse, a selfish person is most likely to sacrifice others to save themselves, as they prioritize their own safety above all else.
Step-by-step explanation:
Discussing who would sacrifice everyone else to save themselves in the event of a zombie apocalypse relates to character types and human psychology rather than an actual event. The person likely to take such an action would be a selfish person. A heroic individual is typically characterized by selfless acts and courage, often putting the needs of others before their own, especially in dire situations like an apocalypse. A team player would collaborate with others for mutual survival, sacrificing personal safety for the group if necessary. A fearless individual might confront the threat head-on but wouldn't necessarily sacrifice others for personal gain; they might be driven by thrill or a sense of challenge. Therefore, the most accurate answer is b. Selfish person. This character type is mostly concerned with their personal wellbeing, even at the expense of others, and would likely take any opportunity to ensure their own survival, even if that means sacrificing others.
